Overview

The use of lubricating greases is essential across a wide range of industries. Composed of a base oil, a thickener and other additives, a grease reduces friction and wear of equipment, protects against rust and corrosion and acts as a seal against dirt, water and other contaminants. Our PURASIL® silica’s are effective thixotropes that can be used to thicken a range of base oils and improve the performance properties of greases.

​

Base oils have different properties, whether they are mineral oils, silicones or synthetic oils. Using the optimal PURASIL® product creates a particle network, enabling more tailored performance. PURASIL® silica performs well in a range of base oils and is widely used in dielectric greases, damping greases, vacuum greases and food grade greases.

​

PURASIL silica can enable:

• Efficient thickening

• Low oil bleed

• Good reversibility

• No dropping point

• Water resistance

​

Our silica forms a physical network of particles that thicken a base oil. The network formed allows for high levels of thixotropy and reversibility in the base oil. In addition to providing good thickening and stability, and allowing the system to exhibit elasticity to large strains, silica can also be used as a thickening additive in formulated greases. As an additive to formulated greases, silica can provide an additional level of rheological tailoring.
